Inductance Evaluation and Sensorless Control of a Concentrated Winding PM Vernier Machine

Due to the advantages of high torque density and simple mechanical structure, permanent magnet vernier (PMV) machines have attracted more and more research interests. In this paper, the inductance nonlinearity of an advanced concentrated winding PMV machine is investigated with consideration of both magnetic saturation and cross-coupling saturation under different d-axis and q-axis current loading...
